Answer:

  • See below

Step-by-step explanation:

  • Given details help to determine the function only.
  • There is no relationship between the mileage and future cost.
  • We only consider the current price, decay rate and number of years.
<h3>Car A</h3>
  • Cost = 8750
  • Year of Manufacturer = 2015
  • Decay factor = 12% or 0.12

<u>The function would be:</u>

  • f(x) = 8750*(1 - 0.12)^x = 8750*0.88^x, where x is the number of years since year 2015
<h3>Car B</h3>
  • Cost = 9995
  • Year of Manufacturer = 2017
  • Decay factor = 18% or 0.18

<u>The function would be:</u>

  • f(x) = 9995*(1 - 0.18)^x = 9995*0.82^x, where x is the number of years since year 2017

In a batch of 100 parts, 40 are red, 50 are L-shaped and 22 are both red and L-shaped. What is probability that a part picked fr
Bogdan [553]

The probability that a part picked from this batch at random is either red or L-shaped is 0.68

Step-by-step explanation:

Let us revise some rules of probability

The addition rules are:

  • P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen  at the same time)
  • P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they  have at least one outcome in common)

∵ A batch has 100 parts

∵ 40 are red

- Probability of an event is the [even occurs/total outcomes]

∴ P(red) = \frac{40}{100}=0.4

∵ 50 are L-shaped

∴ P(L-shaped) = \frac{50}{100}=0.5

∵ 22 are both red and L-shaped

∴ P(red and L-shaped) = \frac{22}{100}=0.22

This is non-mutually exclusive because there is a common between them, so we will use the 2nd rule

∵ P(red or L-shaped) = P(red) + P(L-shaped) - P(red and L-shaped)

∴ P(red or L-shaped) = 0.4 + 0.5 - 0.22

∴ P(red or L-shaped) = 0.68

The probability that a part picked from this batch at random is either red or L-shaped is 0.68

Which one is it A. B. C. or D.
nadya68 [22]
7x + 2y = 2
2x - y = 10

2y = - 7x + 2
- y = - 2x + 10

2y = -7x + 2
y = 2x - 10

y=\frac{-7x+2}{2}
y= 2x - 10

y = -3.5x + 1
y =  2x - 10

Now, let's find "x" first by doing a substituion !

2x - 10 = - 3.5x + 1
y = 2x - 10

2x + 3.5x = 1 + 10
y = 2x - 10

5.5x = 11
y= 2x - 10

x =  \frac{11}{5.5}=2
y= 2*2 - 10 = 4 - 10 = -6

In short, the answer would be : y = -6 (Option B).

Hope this helps !
